noun 1. the power or property of resistance. 2. Also called specific resistance. Electricity. the resistance between opposite faces of a one-centimeter cube of a given material; ratio of electric intensity to cross-sectional area; reciprocal of conductivity.noun 1. the electrical property of a material that determines the resistance of a piece of given dimensions. It is equal to RA/l, where R is the resistance, A the cross-sectional area, and l the length, and is the reciprocal of conductivity. It is measured in ohms ρ Former name specific resistance 2. the power or capacity to resist; resistance resistivity (rē’zĭs-tĭv’ĭ-tē) A measure of the potential electrical resistance of a conductive material. It is determined experimentally using the equation ρ = RA/l, where R is the measured resistance of some length of the material, A is its cross-sectional area (which must be uniform), and l is its length. It is measured in ohm-meters.

noun, Electricity. 1. a device designed to introduce resistance into an electric circuit. noun 1. an electrical component designed to introduce a known value of resistance into a circuit resistor (rĭ-zĭs’tər) A device used in electrical circuits to maintain a constant relation between current flow and voltage. Resistors are used to step up or lower […]

noun 1. a fabric-printing method in which a dye-resistant substance is applied to certain specified areas of the material prior to immersion in a dye bath and subsequently removed so as to permit the original hue to act as a pattern against the colored ground.
